What is GSM?
GSM simply stands for grams per square metre and describes the weight of the filling within the mattress itself. In other words, GSM is the density of fibres within the mattress.
The measurement of GSM is rooted in the craft of upholstery and provides an accurate summary of the density of a mattress. The key thing to note is that the higher the GSM, the higher the quality of the mattress.
It also provides a standardised benchmark that allows manufacturers to easily compare the density of mattresses, even if they’re made from different materials. Whether a mattress is made from white fibre, wool, horsehair or even a combination of fibres, GSM provides a simple like-for-like comparison.
However, many mattress retailers fail to pass on GSM measurements to their consumers. Unfortunately, they know that they can sell lower quality mattresses at a higher price to increase their profits.
Without understanding GSM, you can easily fall into the trap of paying more for a mattress that is actually worth less. Therefore, it’s crucial that you find out the GSM of a mattress to ensure that you’re getting the best possible value.
